This invention relates to battery terminal clips, and contemplates astructure by means veniently associated with or removed from the post ofthe battery wlthout requiring the use of tools for this purpose, and onewhich can be effectively and umformly clamped about the post.

The nature and advantages of the invention will be better understoodwhen the following detail description is read 1n connection with theaccompanying drawing, the invention residing in the construction,combination and arrangement of parts as claimed. I

In the drawing forming part of H118 application like numerals ofreference indicate similar parts in the several views and where- 1n:

Figure 1 is a fragmentary view of a battery showing how the clip isassociated therewith.

Figure 2 is an edge elevation of the clip looking at one side thereof.

Figure 3 is a similar view looking at the other side.

Figure 4 is an end elevation taken at right angle to Figure 1.

Referring to the drawing in deta1l A 1ndicates generally a battery ofany well known construction and wherein 10 represents one of the poststhereof.

The clip forming the subject matter of the present invention embodiescompanion sections 11 and 12 respectively, both of which are designed toconform to the shape of the post with which they are adapted to beassociated. Carried by the section 12 is a loop-like extension 13 toaccommodate the wire 14, while the adjacent corresponding extremities ofthe companion sections are arranged in spaced parallel relation. Theextremity 15 ofthe section 11 is provided with an opening 16, thediameter of which is slightly larger than the diameter of the bolt 17which is adapted to be passed through this opening, and through acorresponding opening 18 in the adjacent extremit of the section 12. The10011: is threaded into the last mentioned opening, but by reason of thediameter of the opening 16 with relation to that of the bolt, thesection 11 is permitted sliding movement upon the latter. The bolt isprovided with a head 19, and interposed between the latter and theextremity 15 of the section 11 is a coil spring 20 which yieldablsupports the section 11 in i re latl dn with-the section 12. TE: therextremlty 21 of thesectionill is provided'with an elon ated slot 22which coincides with I th note 23 formed in the adjacent extremity 4 ofthe section 12, which sections are held associated in o erative.relation by means of a bolt 25 incliiding a squared portion 26 adaptedto be received by the slot 22 above mentioned. This bolt is alsoprovided with a head 27,- while interposed between the latter and theextremity 21 of the section .11 is a coil spring 28-which co-operateswith the sprin 20 above mentioned, to yieldably support t e section 11in clamping relatlon with the section 12. A thumb nut 29 is threadedlyassociated with the bolt 25, and through the instrumentality of whichthe sections of the clamp can be caused to effectively and uniformlyengage the post of the battery. The entire construction is very simple,and is such as to allow the clamp to be quickly associated with orremoved from the post of the battery as the occasion may require, andwithout the use of tools or implements.

In order to associate the clamp with the post, it is only necessary topass the bolt 17 through the openings at one end of the clamp, Whichbolt is as above stated threadedly associated. with the section 12. Thebolt is so arranged as to allow the section 11 to move with relation tothe section 12, while the other ends of the clamp are being con-- nectedtogether. To accomplish this it is only necessary to slip the bolt 25through the other ends of the clamp sections, and then tighten the thumbnut 29, which allows the extremity 15 of the section ll-to slide on thebolt 17 against the tension of the spring 20, so that as the thumb nutis screwed upon the bolt the clamp sections are caused to efl'ectivelyand uniformly engage the post.

While it is believed that from the foregoing description, the nature andadvantages of the invention will be readily apparent, I desire to haveit understood, that I do not limit myself to what is herein shown anddescribed and that such changes may be resorted to when desired as fallWithin the i to embrace, the adjacent end portions of the respectivesections being extended in spaced parallel relation, two of said endshavin aligned openings, one of which is threade a bolt assing throughsaid openings and threade into the latter mentioned opening, the otherend of one section having a slot, the adjacent end of the other sectionhaving an opening, a bolt passed through said slot and opening and havina squared portion arranged in the slot, a t umb nut associated with thebolt, coiled springs surrounding both of said bolts and exerting ressureagainst one of said sections to ermit yieldin movement thereof with reation to the ot er section while the' clamp is being attached to thepost, and a sleeve-like member carried by one of said sections andarranged at a right angle thereto.

In testimony whereof. I aflix my signature.

GEORGE HARDOS.
